DISINTEGRATING lVIACHINE.

SPECIFICATION forming part of Letters Patent No. 423,870, dated March 18, 1890. Application filed December 3, 1889. erial No. 382,378. (No model.)

To an whom it may concern:

Be it known that I, JOHN W. HYATT, a citizen of the United States, and a resident of Newark, in the State of New Jersey, have invented certain new and useful Improvements in Disintegrating-Machines, of which the following is a specification.

These improvements relate to the class of disintegrating-machines in which the shredding operation is performed by a system of so-called drunken saws, consisting of a series of circular saws mounted upon a common shaft in planes which are parallel with each other, but which diagonally intersect the sh aft upon which the saws are mounted.

The invention embraces certain feeding, guiding, and stripping devices, and the combination of said devices, respectively, with a system of drunken saws in a machine for disintegrating sugar-cane and other woody or vegetable material.

The accompanying drawings of a machine containing the invention are as follows: Figure 1 is atop view, partly in section. Fig. 2 is a rear elevation. Fig. 3 is an end elevation. Fig. at is a front elevation of the rotating feeder, showing its strippers and some of the adjacent portions of the machine. Figs. 5 and 6 are respectively an elevation and a top view of the guiding-blades forattachment to the feed-table. Figs. 7 and 8 are respectively a view of the edge and of the face of one of the stripping-plates for the rotating feeder. Figs. 9 and 10 are respectively a side elevation and a top view of one of the laterally-vibrating supporting-fingers. Fig. 11 is a transverse vertical section of the machine, taken through the plane indicated by the dotted line 5c 00 on Fig. 1. Fig. 12 is a top view of the drunken saws, illustrating a modification of the supporting and stripping fingers, which consists in making them in one piece with or rigidly affixing them to an endwise-movable bar.

The machine represented in the drawings embraces a saw-shaft A, provided with suitable bearings a a in the frame 13, and with a driving-pulley A for the reception of the belt by which the saw-shaft is rotated. The sawshaft A carries a system of drunken saws, which, as heretofore ordinarily constructed,

is composed of a series of circular saws O, equidistantly mounted upon the saw-shaft in planes which are parallel to each other, but which diagonally intersect the shaft. The saws are separated from each other by means of interposed washers or disks, and are clamped together between collars aiiixed to the shaft in the usual manner.

' The sugar-cane or other materialto be disintegrated, which is hereinafter called simply the cone, is deposited upon the deliverybelt D, by which it is carried to and delivered upon the table D in position to be caught by the rotating feeder E, and fed forward forcibly against the saws. The rotating feeder which it is preferred to employ in itself constitutes one part of the present invention. It is composed of aseries of star-pointed wheels made of sheet metal, which are loosely mounted and keyed upon the horizontal shaft E, provided with bearings E in the frame of the machine and rotated by means of the sprocketwheel E to which the sprocket-chain E is applied. One of the said star-pointed wheels 6 is shownin detail inFig. 11. 'It has a hole through it and an inwardly-projecting tongue 6, which, when the star-wheel is slid 011 the shaft E, projects into the groove e formed longitudinally in the surface of the shaft E The tongue 6 is loosely contained within the said groove c3, and thus permits the starwheel to'slide longitudinally upon the shaft E, but serves as a key which compels the star-wheel e to partake of the rotatory motion of the shaft E, The star-wheels are kept equidistantly separated from each other by means of the system F of the strippingplates f, which are rigidly secured to the horizontal girder F, bolted at its opposite ends to the frame of the machine. This construction permits the star-wheels to be readily assembled upon the shaft which drives them, and, in case one of them shouldbreak, greatly increases the ease with which the broken star-wheel can be removed and another one slipped on the shaft. fore, that the plates f have an important relation to the structure by reason of the double function which they perform of strippers and of spacers for keeping the loose star-wheels in their proper relative positions.

It will be seen, there-.

The stripping-plates extend downward from the girder F into the spaces between the star-wheels, respectively, and partially embrace the shaft E. Each of them is preferably provided at its lowerend with the downwardly-projecting blade f, having its sharp under edge downwardly inclined toward the saws, as shown in detail in Figs. 7 and 8.

The top of the table D is preferably in the plane of the axis of the saw-shaft A. At the side of thetable D toward the saws it is provided on the top with a series of vertical guiding-blades d, the sharp upper edges of which incline downwardly and outwardly from the saws. The vertical planes of these guiding-blades are parallel with the planes of the star-wheels and perpendicular to the axis of the saw-shat t A. The inner edge of the table D is at a sufficient distance from the saws to afford clearance for them; but in order to atford a support for the material which is being disintegrated, which shall extend beyond the inner edge of the feed-table, there is provided a system of laterally-movable stripping fingers 71, which project,respectively,into the spaces between the saws, and act not only as strippers for the saws, but as supporting-[ingers, which detain the short pieces or buttends of the cane and prevent them from falling down into and clogging the spaces between the saws. The supporting-fingers may be rigidly attached to a horizontal bar II, as is represented in Fi 12, to which endwisereciprocating motion is imparted by the wabbling action of the saws upon the fingers and upon the shoulders 11 and Il which respectively bear upon the outer sides of the outermost saws. It is preferred,however, to make the stripping and supporting fingers 7L independently movable, which is conveniently effected by pivotally connecting their outer ends h with the top of the horizontal girder I, which is arranged beneath the table D, and bolted at its opposite ends, respectively, to the end standards 7) I) of the machine. The inner portions of the fingers 72 are provided with the upward offsets 71?, the upper edges of which are substantially on a line with the surface of the table D.

It will be seen that it is the offset portion of each of the fingers 7i which projects into the space between the saws, and these portions are provided upon their opposite sides with the rounded bosses 71* 71 for hearing against the sides of the saws, respectively.

The saws are preferably protected at the top by the hinged shield A A separate driving-shaft L is preferably employed for driving all the moving parts of the machine, except the saws, and is itself rotated by a belt applied to the pulley L. The driving-shaft L is provided with a sprocket-wheel E for engaging the sprocket-chain E, which drives the rotating feeder E, and is also provided with a sprocket wheel d for driving the sprocket-chain (P, which engages the sprocketwheel (1, afiixed to the counter-shaft (i from which motion is imparted to the delivery-belt D by the engagement of the spur-wheel (1 with the pinion (7., affixed to the shaft of the driving-roller (I of the delivery-belt D, which is an endless belt stretched over the drivingroller (1 and the stretching-roller (1. Motion also taken from the driving-shaft L, by means of the miter-gears Z Z, to rotate the driving-roller N of the discharging-apron n, stretched across beneath the saws over the driving-roller N and the stretching-roller N.

As will be seen, the saws operate to make a wide cut, owing to their diagonal. positions with relation to their axis of rotation.

In operation the cane, forcibly fed against the drunken saws by the rotating feeder, is prevented from yielding laterallyto the wabbling action of the saws by the vertical yielding blades (7, which, in addition to affording lateral support for the cane, serve to guide it in paths perpendicular to the axis of the saws.

The laterally-movable strippingfingers It may of course be arranged in a different part of the machine-as, for example, on the side of the drunken saws opposite that where the cane is delivered. They would in such case perform their stripping functions with equal effect; but by placing them in the position shown those portions of them which project into the spaces between the saws constitute extensions of the supporting-table and perform the additional function of supporting any short pieces of cane which in y collect in the spaces between the saws, and of detaining such pieces in position where they will be subjected to more or less abrading action by collisions with the sides of the saw-teeth. The shredded cane falls from the saws upon the discharging-apron 12, by which it is discharged at the side of the machine, where convenient access can be had to it.

It will of course be understood that if the machine is in an elevated position the discharging-apron n can be dispensed with and its place taken by a hopper placed beneath the saws for catching the shredded cane and guiding itinto a chute for conducting it to a bin or any other receptacle which may be provided for it.
